Zetroc806 Posted July 31, 2022 Share Posted July 31, 2022 (edited) I ordered a wilwood brake conversion kit for a 1964 Buick riviera. Went to split the axle and the flanges don’t match up to the wilwood kit. Would anyone now what axle and housing I’m looking at. I added pictures for references. The diagram is the one wilwood said it would be. Edited July 31, 2022 by Zetroc806 (see edit history) Link to comment Share on other sites More sharing options...
joe_padavano Posted July 31, 2022 Share Posted July 31, 2022 None of these aftermarket companies understand GM rear axles from the 1960s. That diagram for the 1964-70 BOP axles is for A-body cars, because aftermarket companies think that GM only built A-body cars in those year. Your 64 Riv has the original Buick rear axle, and I can guarantee that no aftermarket brake company even knows this axle exists. 2 Link to comment Share on other sites More sharing options...
rocketraider Posted July 31, 2022 Share Posted July 31, 2022 Scroll down the Forums till you find the Buick Forums, then post this question in the Riviera subforum. They can ID your rear end and probably advise if there's a bolt-on rear disc kit available, or how to adapt one. Too many people also believe that not only did GM not build anything but A-body cars in 60s, but that they didn't build cars at all after 1972.
